AX3482S中文资料亚瑟莱特数据手册PDF规格书

 GENERAL DESCRIPTION

The AX3482 is a monolithic synchronous buck regulator. The device integrates two 130mΩ MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-Cycle current limit.

An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1μA.

This device, available in an 8-pin SOP package, provides a very compact solution with minimal external components.
